Where to Terminate the Stego Wrap

Always consult the project design team for where to terminate the vapor barrier to strike the balance between the location of the vapor barrier on or around foundation constructions and any structural concerns before proceeding.

ASTM E1643 provides direction on where to terminate the vapor barrier as follows: ASTM E1643, Section 6.4 - Extend vapor retarder over footings and seal to foundation wall, grade beam, or slab at an elevation consistent with the top of the slab or terminate at impediments such as waterstops or dowels... ASTM E1643, Section 6.6 - Extend vapor retarder over the tops of pile caps and grade beams to a distance acceptable to the structural engineer. In accordance with ASTM E1643, terminate the Stego Wrap as follows:

At an elevation (height) consis tent with the top of the slab;

Note: Turn Stego Wrap up foundation walls or forms.

At Impediments; OR

Note: Impediments may include rebar, dowels, water stops, etc.

At a location of termination designated by the project design team.

Note: The distance to which the vapor barrier is extended adjacent to, onto, or completely over a footing or grade beam should be determined by the project design team.

If the location of vapor barrier termination has not been clearly addressed in the construction documents, then clarifi cation should be requested from the project design team. Should no direction be given, Stego recommends the project team follow the guidelines of ASTM E1643. Regardless of where the vapor barrier is determined to be terminated, ASTM E1643 requires the terminating edges to be sealed. See Sealing Stego Wrap at Terminating Edges, next page.
